[PATCH 0/1] virtio-pmem: Support PCI BAR-relative addresses

[tstark@linux.microsoft.com]

From: Taylor Stark <tstark@microsoft.com>

This patch updates the virtio-pmem spec to add support for describing the pmem
region via PCI BARs. This is required to support virtio-pmem in Hyper-V, since
Hyper-V only allows PCI devices to operate on memory ranges defined via BARs.

As virtio-pmem hasn't been added to the virtio spec yet (see this issue [1]),
this patch is based off the RFC spec [2]. The linux driver implementation has
been posted at [3].
